n lThe present improvement relates to the construction of a movable panel unitfor metallic building structures and is especially desirable fora panel unit containing glass because a panel unit made according to this invention can be shipped, stored, erected or moved without disturbing the putty, in other words it is completely glazed.

It is\ among the objects of this invention to provide aconstruction which is simple and convenient for manufacture, strong and durable, consisting `of few parts and pleasing in appearance, especially by the avoidance of exposed welded joints. Other objectsl and advantages will appear as the description procefeds.

The invention consists of the features hereinafter described and particularly pointed out in the claims; the following description and the annexed drawings setting forth but one illustrative embodiment of the various forms in which the principle of the invention may be applied.

In said annexed drawings Fig. 1 is a perspective view of a panel unit constructed according to this invention.

Fig. 2 is a vertical section thru upper horizontal member of such unit.

Fig. 3 is a horizontal section thru the joint between the stile and chair rail being parts of such unit.

Fig. 4 is a fragmentary broken perspective Iview of the joint shown by Fig. 3.

The gures disclose panel unit 1, being shown for convenience as containing one glass panel 2 and one steel panel 3, and having vertical stiles 5, upper horizontal member 4, chair rail 6 and bottom rail 9.

Each vertical member or stile 5 is formed with a deep U shaped lon 'tudinally extend- Said stile 5 has cleats 8 (see Figs. 3 and 4) struck up on the panel facing side at the locations desired tting within the cross members 4, 6, 9 of the panel unit 1 and thereby preventing either the rotation or dislocation of said cross members either laterally or vertically with respect tothe stile. Holes are provided in the bottom of the aforementioned panel holding grooves 7 in the stiles 5 at suitable locations for tie rod bolts 10,1so located as to be concealed within the boundaries of the cross members 4, 6,' 9.

By' locating said `tie rod bolts 10 at each cross member 4, 6, 9 it is possible by drawing up on s aid bolts to produce tight -joints between the interlitted ends of the cross members 4, 6, 9 and the face of the stile 5, .it being noted that in this construction illustrated such ends requiresimply to be square cut in order to obtain a perfect joint. vIn other words, the construction here shown is desirable because there is no necessity for mitering any joints between stile and cross members. Furthermore the tie rod bolts bind the panel unit together in a strong, durable and inexpensive Tnanner without the use of welding, brazing, seaming or riveting and the bolts asl previously stated are entirely concealed. The panel unit may remain bolted together during shipping, storage, erection or moving; but if due to accident it is desired to replace any one or more elements of said panel unit or if it is desirable to 'changethe width or ter than the width of .thel groove 7,"and it is not desirable to weaken the stile, these holes or passages are formed byembossing or expanding the edges of the groove outwardly at such point, as shown in 4. This provides a strong construction without loss of metal.

To provide for conveniently reglazing said panel unit l, when necessary, the upper horizontal member 4 of all glazed panel openings is bipartite, constructed Vof a fixed portion 4 and a frictionally retained removable moldinpo'rtion 12 (seeFig. 2). i

o insert a glass panel 2 in a panel unit 1, having removed the molding 12, the glass 2 is inserted in the before-mentioned deep U- shaped groove 7 in onel stile 5 whereupon the glass 2 can be swung into alignment with the .panel holding grooves 7 in both-StilesI 5; the

deep U-shaped groove 7 having provided room enough for the admission of sucient width of glass for that purpose. The molding l2is then pressed into position and the putty applied.

Inasmuch as one of the chief purposes of a glazed partition is to transmit light, a glazed panel unit constructedaccording `to this invention is especially useful because the stiles thereof are narrow and consequently present a minimum of obstruction to light and bechauseof the rigid construction of said panel units they may be installed as close to one another as desirable even without the inter- .'position of a stud therebetween.

both ends and has nuts applied thereto. Thisv construction may of course be varied by having one end of the rodvformed into a head or bent over in the form of a hook.'

Other modes of applying the principle of this invention may be employed instead of that explained, changebeing madeas regards the features herein disclosed, provided the means stated by any of the following claims or thel equivalent of such stated means be employed.

I therefore particularly. point out and dis.

tinctly claim as'my inventionl. In a metallic partition assembly, units comprising channel-shaped sheet metal verticals presenting grooves; grooved hollow horizontal cross members extending between positioning cleats on the web portions of such verticals, one of such horizontals presenting a vmovable portion to allow insertion of a stretcher in .such grooves; tie rods extending between the web portions of such verticals;

and wiring holes leading from within such horizontals through the verticals and formed by lateral displacement of the' walls of the vertical grooves.

2. In a metallic partition; units comprising panel plates, sheet metal channel frame verticals each having a groove, hollow horizontals extendin lbetween the verticals on opposite sides of t e panel plates and clamped So, too, the unit may comprisebetween the verticals by tie rods; and holes extending through such verticale into such hollow horizontals said holes being formed by re-forming the side walls of the groove to a greater width than the groove.

3. In a metallic partition construction; panel units consisting of channel-shaped sheet metal verticals with grooves and projections on their web portions; hollow horizontal cross members positioned against said verticals by means of said projections; and wiring holes leading into such horizontals and of greater width than the grooves and formed without destruction of the parallel walls of the grooves.

4. In metallic partition construction; panel units comprising channel-shaped sheet metal verticals having grooves on their web portions; hollow horizontal cross'members extending between the web portions of such verticals; tie rods within said cross members and clamping them between the web ortions of such verticals; and holes leading rom the interior of such horizontals through the webl portions of such verticals and traversing the grooves, said holes bein wider than the grooves and formed by displacement of the walls of the grooves.r

5. In metallic partition vertical channel members having fianges and grooved webs; horizontal hollow grooveproviding members engageable between webs of pairs of said vertical channel members; panel membersA carried by the grooves in said vertical channel members and said horizontal members; and wiring holes leading from the interior of such horizontals through the grooves in said verticals, such holes being of greater width than the grooves and formed by displacement of the walls of such grooves.
